Well i'm using it.
Actually there only are 2 problems with this build (for me this is a verry good early build).

problem 1 : Sorry but you asked ...Battery is worst i ever had (no complaining though , i took the jump). Lost 50% within 2hour.
problem 2 : Bluetooth does not work...For me that is not a big issue but it may be for a lot of people...

Hopefully it helped you out a bit.

Yup I'm also using it on my daily z10, I have one question for you.... How are your charge times looking? My first charge took me about 4 hours, and it just reached 80 or so %, even worse is that I'm using the Playbook charger would charges about twice as fast lol. How is yours thus far?

This is a great feature but I think they need to add a camera button as well. I don't know how many times I have ask someone to take a picture for me and they would be looking for a button to push. With this new feature, I'm sure people who aren't familiar with BB10 will push the video dot by mistake.

If you ever find a way to save BBM chat history, and reliably so, let me know. It's the one thing that stopping me from checking out this leak. Hard to believe that BBRY has not made this [saving and restoring chat messages] possible as yet.

When I do a leak like this though I do not want to restore my settings/data...I like a fresh start...although BBM chats should be saved to the BBID in the cloud so users can access it still!! My confusion is that when you update to a new update it repopulates bbm chats...or lets say you switch devices...it repopulates...so it MUST be in the cloud somewhere if it can repopulate on a new device if you do device switch?? Unless it saves the chat history as a file and uploads that to the new phone?

I have backed up and restored and lost all BBM chats. Other times it restores with one or two. The lack of consistency drives me nuts but what seems clear to me is that there are no guarantees that restoring will repopulate BBM. This makes no sense especially because BBM gives the option to save chats.

Warning... take this with a boulder of salt... considering Bla1ze's post re: PlayBook 10.3 and what I just discovered.

I have hope that there's new PlayBook goodness coming. I just tried to bridge using the latest BB Bridge app on this OS, and guess what, can't do it. I get a message saying that I have to update my PlayBook to use bridge. Could mean nothing, could mean something. So basically, what I'm saying is nothing really.

Would be awesome if someone posted more pics or maybe an in depth video, more in depth than the one in N4BB, not only telling the new features but actually showing it in action to everyone. (maybe I asked for too much)
